I do wonder if that's even legal. Our cash clearly says that "This note is legal tender for all debts, public and private." While businesses may have the right to refuse cash, can a government outlaw the use of cash? That seems pretty extreme.

The state representative behind the bill, Rickey Hardy, seems to think it's no big deal, admitting that this is purely to make life easier for law enforcement in response to criminals who steal stuff and then sell it off:

"It's a mechanism to be used so the police department has something to go on and have a lead," explains Hardy.

You can understand why law enforcement wants that, but just because law enforcement wants details of your private transactions, it doesn't mean you should be blocked from using cash. And people wonder why there was so much interest in Bitcoin (even if Bitcoin itself is rather flawed).
